Tony Romo through the years

"I worked as hard as I could," the quarterback said Sunday at the Dallas Cowboys' training camp in Oxnard, Calif. "I took that approach every day I woke up. I had to improve not just a little but a lot each day. I think that helped me get ready for today and hopefully for the beginning of the season."

Cowboys coach Jason Garrett said the team planned to "err on the side of caution" with Romo during camp.

As for the minor kerfuffle of Romo's weight -- which strangely became a topic of conversation at the camp this past weekend when the Cowboys listed him at 236 pounds -- Garrett said Romo was one pound over his "prescribed playing weight."

Romo disagreed with the listed weight, saying he started the team's first practice between 227 and 230 pounds "depending on the day you catch me."
